A set of 58 Coronal Mass Ejections (CMEs) with different kinematics near the sun in LASCO Field of view (FOV) is classified into two groups (i) CMEs which are accelerating (group-I) and (ii) CMEs which are decelerating (group-II). We analyze their interplanetary propagation characteristics to study the distinction between these two groups of events. Some of the following deviations are noted between the two groups as: (i) While group-II events have greater mean values of Standoff distance, Standoff time than the group-I events, the mean transit times of ICMEs and IP shocks are relatively lower for them. (ii) Group-II events are more (30%) radio-rich than the group-I (10%) and they are associated with type II solar radio burst in lower corona, (iii) The possibility of having excess magnetic energy that supports the propagation of CMEs to some extent is studied using estimated speed (VEST) and it is found that a slightly more number of events in group-I (48%) has VEST > VLASCO than group-II (33%). (iv) Net interplanetary acceleration is positive for 35% and 19% in group-I and group-II events respectively. (v) It is also found that ICME/IP shock characteristics of the two groups depend strongly on the CME acceleration.

加速和减速 CME/冲击的行星际特征的区别

在 LASCO 视场 (FOV) 中，一组 58 个在太阳附近具有不同运动学的日冕物质抛射 (CME) 被分为两组 (i) 正在加速的 CME (group-I) 和 (ii) 正在减速的 CME (第二组）。我们分析了它们的行星际传播特性，以研究这两组事件之间的区别。两组之间存在以下一些偏差： (i) 虽然组 II 事件比组 I 事件具有更大的对峙距离、对峙时间的平均值，但 ICME 和 IP 冲击的平均传播时间相对较低为他们。(ii) II 组事件比 I 组 (10%) 更富含无线电 (30%)，并且它们与下日冕中的 II 型太阳射电爆发有关，(iii) 使用估计速度 (VEST) 研究了在某种程度上支持 CME 传播的过剩磁能的可能性，发现 I 组中稍多的事件 (48%) 具有 VEST > VLASCO比组-II (33%)。(iv) 在 I 组和 II 组事件中，净行星际加速度分别为 35% 和 19%。(v) 还发现两组的 ICME/IP 冲击特性强烈依赖于 CME 加速度。
